THOMAS S. GORE, OF JERSEY CITY, NEW JERSEY.

STOVE.

Specification of Letters Patent No. 9,969, dated August 30, 1853.

To all whom it may concern Be it known that I, THOMAS S. GORE, of JerseyCity, in the county of Hudson and State of New Jersey, have invented anew and useful Improvement in Hot-Air Stoves; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, in which Figure 1, is a vertical section of the stove,taken through the center. Fig. 2, is a horizontal section of the same,taken at any point above the foundation or base. Fig. 3,

is a front View of the base; the front plate being removed in order toshow the interior. Fig. 4c, is an external view of the same; a portionof the external case being broken in order to show the arrangement ofthe doors.

Similar letters of reference indicate corresponding parts, in each ofthe several figures.

The nature of my invention consists in surrounding an inner cylinder orchamber of the stove with spiral flues, so arranged or connected to thebase, that the heat which passes down the spiral lines will meet orunite with a main flue or pipe connected to the ordinary smoke pipe. Thearrangement of the spiral fines and base, by which a large heatingsurface is obtained, as will be hereafter shown, constitutes theinvention.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents the fire-chamber, atthe bottom of a cylinder, B; and, C,is a smoke pipe aperture at its upper parts.

D, is a cylinder that surrounds the cylinder, B, forming a space, (a),between them.

The cylinder, D, extends downward to the bottom of the base, E, of thestove, and the lower end of the space, (a), communicates with theexternal air, in order to allow cold air to pass into the space, (a), asindicated by arrows, 1, in Fig. 1. The cylinder, D, is surrounded by twospiral flues, F, F, which communicate with the upper part of thecylinder, B, by small pipes or passages, (79), (5), see Fig. 1, whichpass through the space, (a). The lower ends of the spiral finescommunicate with the base, E, in the following manner. The front flue isconnected with a passage, (0), in front of the fire-chamber, A, andabove the ash-pit or drawer, G. This passage, (0) communicates with thebase, E, on the outer side of the cylinder, D; see Figs. 2 and 3. Theback flue is connected with a passage, at the back of the fire chamber.This passage, (d), communicates with the base, E, on the outer side ofthe cylinder, D; and the heat from this back flue passes around to thefront of the base, and enters a passage, (c), underneath the ashpit ordrawer, G, and passes out at the back, when it unites with the heat thatpasses down the front flue, see Figs. 1 and 2; the arrows, 2, indicatingthe direction of the heat of the front flue, and the arrows, 3, ,of theback flue. The heat from both of the spiral flues enters the pipe, II,seen in Fig. 4, at its lower end. At the upper end of the pipe, H, asmall pipe, I, is connected, which, when a damper is turned, afiords adirect draft from the fire chamber; the heat not passing down the spiralfiues. The aperture, C, of the pipe, I, is seen in Fig. 1.

J is the outer or external covering which surrounds the cylinder, D, andspiral flues, F, F. As the spiral flues project outward some distancefrom the cylinder, D, it will be seen by referring to Fig. 1, thatspiral spaces are formed around the cylinder, D, between the two spirallines. These spiral spaces communicate with the external air, by meansof openings or holes, (f), seen in Fig. 2.

The advantages of the improvement will be readily seen. Fire being madein the fire chamber, A, and the damper in the pipe, I, being turned, theheat and smoke pass upward in the cylinder, B, and through the smallpipes or passages, (b), (6), into the spiral flues, F, F. The heat andsmoke then pass downward in the spiral flues, as before described, andunite at the back part of the base, E, and ascend the pipe, II. Cold airenters the lower end of the space, (a), between the cylinders, B, D, asindicated by arrows, l, and ascends upward, becoming thoroughly heated.Cold air also passes through the apertures or holes, (f), and ascendsupward through the spiral spaces between the spiral fiues, F, F, andunites at the upper part of the case, J, with the air that passed upwardin the space,

(a). This Warm air is conveyed through proper pipes (not represented,)to any portions of the building designed to be warmed.

K, in Fig. 4, is the door of the external case J. This door, K, isconnected by a Wire or rod, (g), With the door, L, of the cylinder, B,so that by opening or closing the outer door, K, the door, L, is alsoopened or closed at the same time.

By having the fines, F, F, of spiral form, a great heating surface isobtained, and also a great heating space is formed between them for theheating of cold air.

I do not claim the spiral fiues separately, or irrespective of theirarrangement; as they have been previously used; but,
